And I found other codes for the same disease-resistance in Johnny's and Totally Tomatoes. Some are the same; others not. At least 1 (Late Blight) isn't in Totally Tomatoes at all.
And at least one, Southern Blight is listed by Johnny's as Southern Corn Leaf Blight -SCLB even though it affects tomatoes as well as other crops, is only listed by them.
I presume we need to cross-reference various seed sources so a checkbox lists the codes used by various seed sellers.
For instance, FF is used by Totally Tomatoes for Fusarium Wilt - Races 1 & 2; F2 by Johnny's for Fusarium Wilt - Races 1 & 2; F2 by Park's for Fusarium Wilt - Race 2; from above Territorial F2 is only for Race 2 as is Park's.
What do you need from Tatania's TomatoBase? I just got there with IE9 - no problem.
